Mitchell, Synthesis and Structure of a New Family of Cuprate Superconductors: Ln[Sr.
The underlying similarities with the cuprate oxides express a commonality of many of the materials properties and underlying physical concepts in this oxide class of s ystems.
Perhaps the most ambitious goal will be to develop laser-cooling techniques to reduce quantum phase fluctuations between planes of cuprate superconductors.
But until now, the highest-temperature superconducting material was a cuprate that had to be cooled to 164 kelvins.
The cuprate, YBa2Cu3O6+x, is one of the few materials known to be superconductive at higher temperatures, but scientists are so far unable to achieve superconductivity in this material above -179 degree Celsius.
Our understanding of superconductivity in the cuprate family has been hindered by the diversity of intertwining electronic orders," says UBC PhD student Riccardo Comin, lead author on the paper with colleagues at UBC's Quantum Matter Institute, the Max-Planck-UBC Centre for Quantum Materials, and a consortium of research institutions in Canada, the United States and Japan.
Over those twenty years, however, the technology had advanced to the point that the brittle ceramic cuprate compound could be deposited as a thin film on a nickel alloy substrate, providing a potential application medium.
This immense interest in the physics and chemistry communities is reminiscent of the excitement that accompanied the discovery of high - Tc cuprate superconductors in the early 1980s.
The topics include transport properties of high-temperature cuprate thin films as superconductive materials, the liquid-phase epitaxy growth of high-temperature superconducting films, high-temperature Josephson junctions, and microwave filters using high-temperature superconductors.
Topics include electron transport in carbon nanotubes, scattering and pairing in cuprate superconductors, spintronics, single molecule nanomagnets, Fermi-Hubbard physics with atoms in an optical lattice, first-principles calculations of complex metal-oxide materials, x-ray diffraction microscopy, physics of cellular movements, molecular theories of segmental dynamics and mechanical response in deeply supercooled polymer melts and glasses, rheology of soft materials, the mechanics and statistics of active matter, and dynamics of simple cracks.
However, there was disagreement within the scientific community about whether the model encompassed a superconducting state in the typical parameter and temperature range of the cuprate superconductors and, as a result, whether the model was appropriate at all.
This strategy has been used to identify and quantify cation disorder in many complex solids, for example, the thallium cuprate superconductors [Tl.

US patent (13/155,508) titled "Enhancing Critical Current Density of Cuprate Superconductors" discloses a method for enhancing the critical current density in superconductors by restricting the movement of Abrikosov (A) vortices, Josephson (J) vortices, or Abrikosov-Josephson (A-J) vortices using the half integer vortices associated with the d-wave symmetry present in the grain boundary.
Other topics include percolation processes in cuprate composites as low-dimensional systems, crystallizing and characterizing energetic materials, the structure and morphology of eletrodeposited nickel-cobalt alloy powders, developing bulk metallic glasses based on cobalt, graph-skein modules of three-manifolds, and evaluating metal fatigue characteristics considering the effect of defects.
